National Grid stock heads into the open after a 0.4 percent gain

At the close on September 15, 2026, National Grid stock on the London Stock Exchange finished at about 1,110 pence, up roughly 0.4 percent, while the FTSE 100 slipped around 0.6 percent. Today, investors watch the impact of Bernstein's fresh outperform rating.

National Grid stock closed at about 1,110 pence on the London Stock Exchange on September 15, 2026, recording a gain of roughly 0.4 percent versus the previous session. That move came on a day when the FTSE 100 index fell about 0.6 percent, meaning the shares outperformed the wider London benchmark.

September 15, 2026 in numbers

National Grid plc (ISIN GB00BDR05C01, LSE: NG) saw its shares finish around 1,110 pence on September 15, 2026, after trading in a narrow intraday range that left the close close to the session midpoint. Per London market data, the FTSE 100 ended the same session down approximately 0.6 percent, highlighting that National Grid bucked the broader weakness in UK blue chips. Trading volume in National Grid on the day stayed near recent averages, suggesting steady interest rather than an unusually heavy turnover phase.

A key driver for the session was a renewed positive stance from Bernstein. As Investing.com reported on September 15, 2026, the broker resumed coverage of National Grid with an outperform rating and a price target of 1,310 pence, arguing that the utility offers exposure to attractive regulated businesses at an undemanding valuation. In a separate commentary, AskTraders noted that the stock rose about 0.5 percent to roughly 1,110 pence on Tuesday as investors digested the bullish view and the potential upside from decarbonization investments. This analyst support helped underpin the share price even as broader UK equities faced pressure from higher bond yields.

Analyst focus today

Heading into today, the Bernstein call remains a fresh reference point for National Grid, and its 1,310 pence target may frame expectations around the stock. As Investing.com highlighted, the thesis centers on regulated growth, strong visibility and resilience, themes that can be sensitive to moves in interest rates and bond yields. Broader London markets also face ongoing scrutiny of Bank of England policy and gilt yields; Reuters reported on September 15, 2026 that higher oil prices were lifting bond yields and keeping the BoE in focus, a backdrop that can influence regulated utilities like National Grid because of their rate sensitivity. Investors therefore head into the new session watching both company-specific analyst commentary and macro signals from UK bond markets and central-bank communication.
